.LAMP-ADJ'USTING MECHANISM FOR VEHICLES.

Specification of Letters Patent. I Patbnted Fb. 11", 1913.

Application filed September 5, 1912. Serial 1W0. 718,749.

To all whom it may concern:

Be it known that 1, WILLIAM H. S'rnvrns, a citizen of the United Statesof America, residing at Pittsburgh, in the county of Allegheny and Stateof Penns lvania, have in-. vented certain new and use ul Improvements inLamp-Adjusting Mechanism for Vehicles, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a lamp adjusting mechanism for vehicles, andthe objects of my invention are to furnish a vehicle, as an automobile,with positive and reliable means, as hereinafter set forth, for castingrays of light. in the direction in which an automobile is traveling, andto provide a mechanism of the above character that is applicable tovarious types of automobiles.

I attain the above objects by a lamp adjusting or shifting mechanismthat is sim-' ple, durable, and highly efficient for the purposes forwhich it is intended.

The-mechanism is constructed to compensate for the jars and vibrationsbetween the running gear and the main frame work or body of anautomobile, and with the mechanism automatically actuated the chaufieuror driver of a machine can always observe the path to be traversed bythe machine, especially on curved sections of road.

The invention will be hereinafter specifi: cally described and thenclaimed, and reference will now be had to the drawing, where- 1n Figurel is adjusting mechanism, the same, Fig. 3 is a cross sectional view ofa portion of the mechanism, and Fig; 4 is a perspective view ofthemechanism.

a side elevation of the lamp Fig. 2 is a plan of Further describing myinvention in detail with reference to the drawing wherein like numeralsdenote 1 corresponding parts throughout: 1 denotes an axle provided witha conventional form of steering mechanism 2, which includes a transversearm 3 mounta vertical shaft 4: journaled in a bearing 5, carried by oneof the sides of the axle 1. The vertical shaft 4 has the upper endthereof provided with a longitudinal groove 6 and slidably mounted uponthe upper end of said shaft is a crank,

7 that has a tongueextending into the groove 6 whereby said crank willrotate in unison with said shaft. i 8 denotes a coiled compressionspring encircling the vertical shaft 4 between the bearing 5 springholding the crank 7 normally in engagement with a stop 9 mounted upon aside frame 10 of an automobile. -The stop 9 is bifurcated or slotted, asat 11 to provide clearance for the upper end of the shaft 4.

12' denotes a lamp holder pivotally supported upon the frame 10 by a pin13 and this holder supports a conventional form of lamp or lantern 14.The holder 12. has a side extension 15 pivotally connected, as at 16 toa connecting rod 17. The rod 17 is pivotally connected, as at 18 to alever 19 pivotally mounted upon a side of the frame 10; as at 20. Thelever 19 is pivotally connected, as at 21 to a rod 22 that is pivotallyconnected, as zit--23 to the underneath side of the crank 7 When theordinary steering mechanism 2 is moved, the lamp adjusting or shiftingmechanism is actuated to swing the lamp or lantern 14 in the samedirection as the forward wheels. of the automobile. The coiledcompression spring 8 holds the crank 7 normally in engagement with thestop'9', but allows the shaft 4 and the axle 1 to move relatively to theframe 10, without interfering with the operation of the lamp shiftingmechanism.

While in the drawing there is illustrated a preferred embodiment of theinvention, it is to be' 'understoodthat the structural'elements aresusceptible to such changes as fall within the scope of the appendedclaim.

WVhat I claim is In a lamp adjusting mechanism for automobiles, thecombination with an axle having a steering mechanism, a side frame, anda lamp holder pivotally mounted upon said side frame, of averticalrotatable shaft supported bysaid axle and rotated by the steeringmechanism thereof, a crank slidably mounted upon the upper end of saidshaft and capable of rotating therewith, a bifurand the crank 7 saidcompression compressions ring encircling said shaft and retalmng sincrank normally in engagement with said stop, a lever pivotally supportedby said frame, a rod having the ends thereof pivotally connected tosaidlever and to said liimp holder, and a rod having the ends thereofpivotally connected to said crankiand to said lever whereby said lamp Intestimony whereof I afiix my signature in the presence of two witnesses.
